Title: Circuit device for adjusting electronic level of signal
Inventor: THANHEISER WILHELM
IPC: H03G1/04
Filed: 1989-10-06
Abstract: PURPOSE: To prevent any failure due to a click noise by connecting a device for forming a compensating amount with a C MOS switch, compensating a digital step formed by the C MOS switch by the pertinent compensating amount at first, and then continuously decreasing the pertinent compensating amount according to a prescribed time constant. CONSTITUTION: In the static state of a device R, a switch F1 has high resistance, and a switch F2 has low resistance. When a level is steppedly increased at an output side A, a switch stage T2 is closed in a short time, and a capacitor C3 of a timing element R3/C3 is discharged. The switch F2 has high resistance, and the amplification factor of an arithmetic amplifier OP is reduced according to it. The reduction is adjusted by a resistor RG in the following process. That is, the reduction of the amplification factor is equivalent to the size of the step of the level increase, and therefore, the level increase is adjusted so as to be compensated from +1dB to 0dB. After the elapse of a time constant set by the timing element R3/C3, the switch F2 is made to have low resistance again, and as a result, he amplification factor of the arithmetic amplifier OP is turned into +1dB again.

Title: Semiconductor memory device
Inventor: HIGUCHI TETSUO
IPC: H01L21/8229
Filed: 1986-10-31
Abstract: PURPOSE:To enable a high-speed operation by forming an insulating film having a dielectric constant higher than a silicon oxide film in part of the Schottky barrier diode (SBD) of the memory cell section, and adding a capacity CSIN due to insulating film in parallel with the SBD capacity, thereby enhancing the degree of integration and the reliability. CONSTITUTION:Leaving a silicon nitride film 18 in part of an SBD 9a, the remainder is etched away. And arsenic is implanted into the part becoming an emitter region, a heat treatment is implemented to form a N<+> layer, and thereafter the formation is performed according to the prior art process. Since in a semiconductor memory device consisting of such construction, a MIS capacity CSIN due to the silicon nitride film 18 is placed in parallel with the SBD 9a of the memory cell, the total capacity C becomes large, so it will be strongly resistant to the information reversal of the memory cell due to alpha-rays or the like. Further, since CSIN is not placed in the peripheral circuit part, the parasitic capacity does not increase. As the insulating film 18 having a dielectric constant higher than a silicon oxide film is formed in part of the SBD and the capacity CSIN due to the insulating film 18 is added in parallel with this SBD, the reliability can be improved without reducing the degree of integration and the operation speed.
